with an integral .bracket b5 which servesY as a support forthe rmotorfor driving the gearingV in housing b2. Brackets Yo", are integrallyformed with cross-member C o n top. of housingc, to sustain bracketswhich support the upper Astructure of the truck. Elevated I-beams 29are-supported to carry Vthe upper portion ofthe loading elevator,

the riddle and the upper portion of thesandi f elevator. The ends of twoof the I-beams are supported at one side ofthe truck by a bracket 3(7).(Fig. 4) 'which is bolted to the brackets @fof cross-member C,-and therear end of the yother beam 29 is supported by a bracket 33 which isbolted to the top of the,

housingc2 of v,cross-member C. .The front ends of two of said beams aresupported by i a bracket 34 whichis bolted at its lower. ,end

to the top Vof cross-member B. Therfront ends of. said beams are alsorigidly secured r together by a laterally7 extending bracket 35 whichhasdepending gs bolted to all of the A An electric motor-36K(Figs. 2and'4),is

mounted on top of housing c2 of Across-memberC to furnish powerforpropelling the truck4 through variable-speed transmission gearing and ordriving the loading elevator. The shaftoffsaid motor is connected by acouplmg 36` to a transverse shaft 38 which is journalled in bearings39and 40 in the side 'walls of housing c4. Y Shaft 38 has securedtheretohighspeedpinion 41 and a low speed pinion 83. kThe high speed gearingcomprises Y: a lgear 42, which is slidably mounted ona transverse shaft43, which is journalledin bearings '44 and 4 5 in-theside wal1s,f`ofhousing crand has rigidly x'ed theretoa pinion 46, anda gear 47, keyedto a cross-shaft 48", which is mountedin bearings 49Mand the sidel'walls of housing 04. The low speed gearing, operable` by pinion 83,comprises agear 42a which meshes constantly with said pinion and isloosely Y mounted on shaft 43, a pinion 42b rigid with gear 42a, a gear472c meshing with pinion 42b and loosely mounted on shaft 48,"n andv apinion 42d rigidi with gear 42c and adaptedf to be driven by the gear 42when the latter is shifted into one of its positions. A pinion 53, keyedtothe outer end ofjshaftO, meshes with a gear 54 which is keyed to Vthecrossshaft 25 under the cross-memberC.' A similar gear 54 is keyed tothe opposite'end of shaft 25, and these gears mesh respectively withgearsf which 'are bolted to the traction-wheels v,22 respectively. Shaft25 is mounted in bearings 56 in the cross-member C. a c Y A crank 36a isrotatable on'av controller box 3bb which is attached to the rear sideofthe housing o2 (Fig. .1) to control motor `376.

Motor 36 is of the reversible type, so :that it' may be operated inopposite' directions to 'i correspondingly propel the truck. When .the

motorY is to be propelledat ,low speed, gear 42 is disengaged frompinion 41 and shifted into engagement with pinion 42d, so that shaft 48will be driven throughpin'ion 83, gear 42a, pinion 42h, gea-r "42,pinion 4221, gear 42, pinion 45 and gear V,47.r When the truck is to bepropelled at 1nigh speed, gear 42 Vwill be shifted into engagement withpinion 41 on shaft v38, so that shaft 48 will 'be driven through pinion41', lgear 42, pinion 45o-andV stationary or rotating, by a rack 51which is slidablein a bearing 51b and is providedwith a stud laextendingintofan annular groove in the hubv of said gear, and a'pinion 52 whichis adapted to shift said rack.f The transmission is controlled by asprocket-wheel i', which isV fixed to rotatepinion 52, a chain 2, asprocket Sand a hand-wheel 4 which is s fixed to sprocket 3. Hand wheeli4 isadapted to be lcontrolled by an operator on-a platform I which isfixed to one of the frame-plates 20' V(Fig. 1a). An auxiliary platformlvl2, adjacent they controller-box 36h,-is formed on one of the arms 57,anda step I is provided for the convenience of theroperator.

This mechanism exemplifies4 reversible `variable speedtransmissiongearing for proif pelling the truck.

The jib is verticallyadjustable to bodily raise and flower. the projector, member Z2 beingpivoted atcZl" to the socket CZ', and member Z3 being pivotedl at Zu-to'the-member d2, and controlled-by a rod-connection Z12 for that purpose.Conveyor' Z9 is mounted to swing vertically underr the. control ,ofjibmemberfZf. A motor Z13 on-jibmember Z2 is connectedltofop'erate,through suitable gearing, the raising and loweringv cable'cZM. A motorand gearing'in a housing Z15 drives conveyor Z7. The construction ofthis molding machine is more'fully illustrated and described in anapplication filed by us February 13, 1926, Serial Number88,014 nowPatenty N o; 1,717,652, to which 'reference may be had for amoredetailed description. This eX- `emplifies'a'moldingmachine ofthesand-projectorl type which `is mounted on the truck so it can be moved'yfrom place tovplace to fill flasks yon the molding room floor, and isadapted to receive sand from a suppl'yon the truck.

A tank or reservoir E i'sfcarried by the truck and isfadaptedto containaload of sand in sufficient quantity to; fill a\ large ynumber offlasks. rlhe sand fed tothe projector is received from this reservoir.Mechanism F on the truck, for quickly-'loading and filling' thereservoirf'rom a storage pile in,`or adjacent, the foundry', comprisesan elevator which consists of 'a pair of endless chains ff, equippedbetween them with bucle'tsf. These chains -pass around a pairoffdrivefsprockets f4 (Figs.

3 ,andf 4) on cross-shaft f5'journalled in bearings;es fixed toI-beams29 y Chains `fcompriseva vertical loopfto raise the-sandl andahorizontal loop, extending forwardly from sprockets f?, so the bucketswill discharge sand overreservoir E.y Chainsfpass' aroundidler-sprockets f7 which arefiXed to a cross'- sliaft f8' journalled in'bearing-brackets-l f" which areflongit'udinally slidable on two of theI-beams 291 From sprockets f7, the lower 'reaches of chains fpassrearwardly around idler-sprockets flo which are carried by a cross-shaftf, which lis mounted in bearings jm, which arecarried by brackets 30 and33.

' From idlers f1", chains f'pass downwardly aroundxa pair of sprocketsfis'which arefiXed to-drive a cross-shaft fllkwhich is journalled inarms 57, .and thence upwardly to drivesprockets f4. Said armsgarel fixedto arocksliaft58 (Figs. 2 and 3);, which,l is pivoted in lugsc9which'are'inte'grally formed with thecross beam Conveyor screws 59and 60on* shaft flft'convey the4 sand laterally' to the Arms 57 support thecross-conveyor and the lower portion ofthe ofy the cross-conveyor andarms. lA plate 63 extends transversely between sides 61 to confine thesand from passing forwardly under the truck. Arms 57 and sides 61 maybeswung into 'elevated position (dotted linesL Fig. 7), so that thecross-conveyor and the elevator Will'be supported above the molding roomfloor toclear. a pile of sand or flasks on the floor while the elevatoris idle andv the truck is being transported from place'to place.

When the arms 57 and cross-'conveyor are raised, the slack in theelevator chains f will be automatically taken up by shifting the shaftf8, which carries the idler sprockets f7, andis mounted in slidablebrackets ff. Mechanism for this purpose comprises an'arm 64 (Fig. 7)which is integral withone ofthe arms 57 and rigid with shaft 58, so itwill swingl therewith, a link 65 pivoted to'arm 64,

a turn-buckleV 66, a cable 67, which is guided in ay sheave 6,8, whichis-mounted'onialfbe'am 29, a branchk 70 of cable 67, guided byv asheave.71', which is mounted in cross-bar 35 and connected to one of thesliding bearings fg, another branch 72 of' cable 67, which is guidedbysheave 71 and a sheave 7 3which is also mounted in cross-bar 35andconnected tothe other bearing fs, and aspring. tension coupling 74 incable 67. When the arms' 57 are raised (dotted lines Fig. 7, arm 64 willi swing downwardly tooperate "these cable connections, so they willshift forwardly the -7 bearings fg, shaft f8 and sprocketsVt f7 whichcarry the front end of the chains'f, to keepthe chains taut. lStops 671limit the` rearward movement of bearings ff. rIhe shift of'these Ybearings is yieldingly effected lthrough the' spring-couplings 74, sothat the take-up mechanismwill keep the chains tautwithout undue tensionon the chains. A latch 75' (Fig. 7), pivoted as at 76, isadapted toengage a tooth 77 on the rarm 64to lock the arms 57 'and cross-conveyorin raised position and to correspondingly hold these take-upconnections.

Latch 75 iscontrolled by apair ofjlinks'78 l` which are pivoted to saidlatch andto an arm 79 on a' cross-shaft 8O (Fig. 2) which is providedwith a handle 81 by which it may be manipulated by the operator on theplatform I, to lock or release the loading mechamsm. Driving mechanismfor the loading elevator, operable by motor 86,com'prises a clutch 84(Fig. 4), adapted to'be` coupled Vto gear 42a to drive shaft 43, asprocket-wheel lli) 85, fixed to the outer end of shaft 43, sprocketl""i chain 86, driven by sprocket 85, and a sprocket-wheel 87, Which isfixed to drive-shafty f5, to which the drivesprockets .f4 are keyed.Clutch 84 is controllable by the operator on the platform I through arod e (Fig. 1a),

...sin

which is connected `to an arm 7, a shaft is, fixed to said arm,andextended into the housing' c4, and a clutch-shaftingarm 9 xedto theinner end of said shaft.

The raising. of the cross-conveyor and arms .57 andthe lower portion ofthe elevator is effected by power derived from the chains f undercontrol of a brake drum 88 fixed tothe cross-conveyorV shaft f, abrake-band 89,

'adapted to bepapplied yto said drum, and a hand-leverV 90, pivoted toone of the sides 61, and connected to the brake band, so it may betightened to lock the drumragainstrotation i .772590 and'brake-band 89,to permit the crossconveyor to gradually drop into operative position.VThis exemplifies power-operated raising mechanism for thecross-conveyor and the elevator. Y i y Theloading elevator delivers thesand to a riddle Gto condition Yorfdisi'ntegrate the sand for deliveryto the molding machine as itis delivered to the reservoir E. This riddlecomprises a channelled ring g, a'perforated screen gandvangle ironmembers g2 which secure thescreen to ring g. At its front, the ring y Y.p g is suspended by pendant ,links g3 which are ,pivoted to the ring atg4 and to brackets g6 y i fixed to beams 29. At the rear, the riddleV issupported by a vertically extending link or arm 97, which is pivoted atg5 to a bracket g lfixed to ring g. The screen g yis* sloped, so thattheV disintegratedjsand will drop through it into the reservoir E and todischarge the lumps [retained thereby through spouts glo into chutes g11which are each provided with a door gm, so that the screenings can bere- -movedL An inclined chute g1?, under the upperY reach of the bucketsf3, directs the sand into the riddle. I An inclined chute Q13 issupported forwardly of the horizontal loop of Vthe elevator chaintodirect overthrown sand fromthe bucket f3 into the riddle. A Vsheetmetal plate gl* extends under t-he lower reach of the horizontal loop ofthe elevator and in front of the front reach ofthe vertical loop, todirect anyY sand falling from the buckets rearwardly of the riddle backto where it will be again caughtby the elevator. This plate extends'overa tubular strut or cross-member g16 which is secured by U-bolts tobrackets 3033. Mechanism for vibrating the riddle while the elevator isin operatic-n, consists of a wrist-pin gli' (Figs. 3 and 4) on the innerend of shaft 43,'and a'link g1g between said wrist- V1 piny andextensions y19 which are integral with link Q7; When the clutch 82 iscoupled y to drive the loading elevator, the riddle vibrating mechanismkwill: be simultaneously operated. f f

The sand-reservoir E (Figs. 3, 8 and 8a) comprises a stationary cylindere whichvis supported by straps 92, which are fixedrrto bars 28k of thetruck-frame, and a rotatableV bottom-plate e2. Said plate is bolted, ate4,

to an underlying inwardly extending flange of a cast ring e3 which ismounted to rotate horizontally on a series of rollers@6 which are Ycarried by brackets 'e7 which are fixed to the truck-frame. The outermargin of plate e2 and ring e3 are disposed outwardly of cylinder e toform an annular channel around the outside of the lower portion of thecylinder. The lower portion of the wall of the cylinder is curvedinwardly, as at e', (Figs. 5

and 8a), and the topl ofV this curved wall is joined to the cylinder bya horizontal top wall es. This curved wall deflects thersand rest-l Ying on the plate e2, under the influence o-fits rotation, outwardly tothe channel around the outside of the cylinder c, from whichtheA sandwill be elevated for deliveryato the molding machine.

wardly from the cylinder to retain the sand in the channel around thecylinder.

' Mechanism for rotating bottomcz, to cause wall e to force the sandoutwardly, comprises a motor H (Figs. 3 ,and 9), a shaft h, coupled tothe shaft of said motor, and extending into the housing b2 of thecross-'member B; a pinion h', fixed to shaft 7L; a gear h2, meshing withpinion 'ZL' a pinion 7a3-fixed to rotate with gear h2; a gear h4',meshing with A hood 91, rigidY with cylinder e, extends outwardly Vanddownico Y pinion h3 and ixed to a shaft Vh"which is jour-V nalled inhousing b2 (Fig. 9*?) a bevelled pinion las keyed toY shaft h5, abevelled gear h'f fixed to a vertical shaft ha, which is jour.- nalledin bearings'h9 in housing b2 anda gear hn which meshes with. gear teethe formed on the outer periphery of the ring e3.

A feed-'elevator K,for`deliver1ng san from the channel around thecylinder e to the receiving chute Z8 of the moldingmachine, comprises apair of chains kr withV buckets 702, The lower `portions ofl thesechains pass aroundV drive-sprockets lo",v andV their upper Vportionspass around'a magnetic drum c* which is carried by a shaft 105 mountedin arms k6 which are pivoted at k7V to the bracket 35. AV spring ks isapplied to force the arms 706 upwardly to4 keep the chains k taut.Buckets k2 discharge sand (Fig. 8) intoa chute 769 which delivers it tothe receiving chute als of the molding machine. The mag- Y netic drum7c* causes thescrap to be held by the buckets until'they pass away fromthe drum and drop into a suitable chute k1?, to separate the scrap fromthe sand. The lower Zc'g are fixed to a shaft la I in a bearing Z015 inhousing b2 which yis driven i l 1,759,217l

portion of the elevator yextends into the sand-y channel between thering `e3 and the cylinder e, to take sand from the channel. Sprocketswhich is' mounted by a gear 7016 iiXed to said shaft and a pinion lawhich meshes with gear if, which meshes with gear h4 of thebottom-'driving mechanism.` 'The elevatorK will be driven while thereservoir bottom e2 is being rotated.- This constructionexemplieslgearing for driving saidl bottom and said elevator which ismounted in va-housing integrally' formedwith one of the cross-members ofthe truck frame.

Insome' instances, it is desirable to empty the reservoir so that thesand ltherein maybe again passed `through 4the riddle" to vfurtherycondition it., Forthis purpose, a disk'99 is held against the undersideof vreservoirbottomveg, its `margin being supported 'by flanged rollers100 which are Carried byvsaid plate. Openings 101 areformedfin'plate'e2, and disk 99 is for-med with similar A,openings 108,which when iii registry therewith, will permit the sand to drop out'ofthereservoir and onto the molding vroom floor ,between vthe trucksides.Y A channelled cross-bar 102 connects the' truck-,sides under thervreservoir. Normally, that is, while the reservoir is being iilled,.andwhile thesand isf'being delivered to the molding machine by the elevatorK,

openings -101 willy be vclosed vby the disk 99. Stops l105 (Fig. A5) areixed'totlie bottom of disk 99. A-stop-bar 106 is slidably mounted incross-bar 1102 fand provided ywith an abutment 107 which is shi-ftableinto and out of the path of rotation of stops 105 toarrest the disk99vwhilethe bottom e2 isr rotating to open or close the openings 101.Bar V107 isfoperable by a lever 108,'whichis' fulcrumedat 109,andadapted to move the stop-bar106 inwardly or outwardly. Thisexemplifies meansby which'the openings in thebottomof the reservoirA maybe lopened orclosed bypower.

The invention exemplifies a molding ma-Y chine, in which the-truck-frameis composedk ofside plates or bars and cross-memberswith integralhousings; in which power-operated mechanism is providedffor rais-ingandlower ing the cross-conveyor and llower end .of the loading elevator;in which theelevator co`1n, prises a-horizontally extending loopwliichis automatically taken up when the receiving end thereof is raisedor lowered; inl which the rotatable reservoir-bottom is 4extended -toproject beyond the wall of the reservoir to form a channel from lwhichsa-ndis fed tothe molding machine in ywhich -deflectingsmeans for thesand is rigid'withftli'e sand reservoir; in which the transmissiongearing for pro# pelling the truck is housed infone ofthe cross" beamsof the rframe =infwliicfli the-gearing for driving the feed elevator andthe reservoir bottom kare conveniently. yhoused in vone ofthe-cross-beams of thetruckLfra'me lin-'which A in s-aid housing.
